Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a high-strength solenoid valve structure. Background Art

[0002] Solenoid valves are electromagnetically controlled industrial devices, essential automation components for controlling fluids. They are actuators, not limited to hydraulic or pneumatic systems. They are used in industrial control systems to adjust the direction, flow, speed, and other parameters of media. Solenoid valves can be combined with various circuits to achieve desired control, ensuring both precision and flexibility.

[0003] A control box is provided on the outer surface of the solenoid valve, and a PCB board is installed inside the control box. A protective cover is installed at one end of the control shell, and the connecting wires of the PCB board pass through the inside of the protective cover. Most of the existing protective covers are bellows structures. After long-term use, when the protective cover is subjected to force, the corrugations of the protective cover are prone to breakage, thereby causing the connecting wires of the PCB board to be exposed to the outside world and losing its protective effect. To address the above problems, a high-strength solenoid valve structure is provided. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1 - Figure 7 As shown, the utility model is a high-strength solenoid valve structure, comprising a solenoid valve body 1, a control box 101 is provided at one end of the solenoid valve body 1, and a protective sleeve 3 is installed at one end of the control box 101 through a fastening assembly 2;

[0028] One end of the control box 101 is provided with a connection end 102, and the protective sleeve 3 is mounted inside the connection end 102. The outer surface of the protective sleeve 3 is provided with a reinforcing rib 301 and a reinforcing ring 302;

[0029] The force design of the solenoid valve has been optimized, and the main force point has been moved inward toward the valve body axis, significantly shortening the lever arm length. This change effectively reduces the leverage effect at the connection point of the protective sleeve 3. At the same time, the structures of reinforcing ribs 301 and reinforcing rings 302 have been added at the force point of the protective sleeve 3 to ensure that the protective sleeve 3 will no longer break or deform, thereby increasing the practicality of the protective sleeve 3.

[0030] The fastening assembly 2 includes an inner sleeve 201, which is sleeved on the outer surface of the control box 101. An extrusion sleeve 202 is provided on the peripheral side of the inner sleeve 201, and a protective sleeve 203 is provided on the peripheral side of the extrusion sleeve 202.

[0031] One end of the inner sleeve 201 is provided with a connecting seat 204, the outer surface of the connecting seat 204 is provided with an external thread 205, the inner sleeve 201 is provided with an arc-shaped opening 206, and the connecting seat 204 is installed with a protective sleeve 203 through the external thread 205;

[0032] One end of the connecting seat 204 is provided with an annular groove, inside which a fixing ring 207 is fitted. One end of the fixing ring 207 is provided with an extrusion sleeve 202, and the inner surface of the extrusion sleeve 202 is provided with an inclined surface.

[0033] A connecting block 208 is provided on the peripheral side of the extrusion sleeve 202, a mounting groove 209 is provided on the inner surface of the protective sleeve 203, the connecting block 208 is installed inside the mounting groove 209, and a baffle 2010 is provided on the peripheral side of the protective sleeve 203, and the baffles 2010 are set to two and symmetrically distributed.

[0034] When in use, first install the protective sleeve 3 on the connecting end 102, then pass the inner sleeve 201 through the protective sleeve 3 and put it on one end of the control box 101, and put the extrusion sleeve 202 on the peripheral side of the inner sleeve 201 so that the fixing ring 207 is installed inside the ring groove. Since the inner surface of the extrusion sleeve 202 is provided with an inclined surface, the extrusion sleeve 202 gradually squeezes the inner sleeve 201 inward, so that the inner sleeve 201 gradually squeezes the protective sleeve 3 inward, so that the protective sleeve 3 is tightly attached to the connecting end 102, and the protective sleeve 203 is taken out. The mounting groove 209 provided on the inner surface of the protective sleeve 203 is aligned with the connecting block 208 provided on the side surface of the extrusion sleeve 202, and then the protective sleeve 203 is pushed toward the end close to the connecting seat 204 so that the protective sleeve 203 is arranged on the side surface of the extrusion sleeve 202. The protective sleeve 203 is screwed to the connecting seat 204 by holding the two baffles 2010 with the fingers and rotating the protective sleeve 203 counterclockwise. Then, the installation of the protective sleeve 203 is completed. When the fastening component 2 needs to be disassembled, the above steps can be reversed to complete the disassembly operation of the fastening component 2, which optimizes the force design of the solenoid valve, moves the main force point position inward toward the valve body axis, and significantly shortens the force arm length. This change effectively reduces the leverage effect of the connection part of the protective sleeve 3. At the same time, the structure of the reinforcing rib 301 and the reinforcing ring 302 is added at the force point position of the protective sleeve 3, which can ensure that the protective sleeve 3 no longer breaks or deforms, thereby increasing the practicality of the protective sleeve 3. The fastening component 2 is set up, and the connection between the connecting end 102 and the protective sleeve 3 can be reinforced, and subsequent disassembly and installation are convenient. At the same time, the connection between the connecting end 102 and the protective sleeve 3 can be protected to prevent external dust or water vapor from entering the interior of the control box 101 through the connection between the connecting end 102 and the protective sleeve 3, affecting the service life of the electronic components inside the control box 101, thereby achieving a better protection effect.
